Utilities for applying backdrop saturation filters to an element.

Default class reference

Class
Properties
backdrop-saturate-0--tw-backdrop-saturate: saturate(0);
backdrop-saturate-50--tw-backdrop-saturate: saturate(.5);
backdrop-saturate-100--tw-backdrop-saturate: saturate(1);
backdrop-saturate-150--tw-backdrop-saturate: saturate(1.5);
backdrop-saturate-200--tw-backdrop-saturate: saturate(2);

Usage

Use the saturate-{amount} utilities alongside the backdrop-filter utility to control an element’s backdrop saturation.

<div class="backdrop-filter backdrop-saturate-125 ...">
  <!-- ... -->
</div>

Responsive

To control an element’s backrop saturation at a specific breakpoint, add a {screen}: prefix to any existing backdrop saturate utility. For example, use md:backdrop-saturate-150 to apply the backdrop-saturate-150 utility at only medium screen sizes and above.

<div class="backdrop-filter backdrop-saturate-110 md:backdrop-saturate-150 ...">
  <!-- ... -->
</div>

Customizing

You can customize which backdrop-saturate utilities are generated using the backdropSaturate key in the theme section of your tailwind.config.js file.

  // tailwind.config.js
  module.exports = {
    theme: {
+     extend: {
+       backdropSaturate: {
+         25: '.25',
+       }
+     }
    }
  }

Learn more about customizing the default theme in the theme customization documentation.

Variants

默认情况下, 针对 backdrop saturate 功能类,只生成 responsive 变体。

您可以通过修改您的 tailwind.config.js 文件中的 variants 部分中的 backdropSaturate 属性来控制为 backdrop saturate 功能生成哪些变体。

例如,这个配置将生成 hover and focus 变体:

  // tailwind.config.js
  module.exports = {
    variants: {
      extend: {
        // ...
+       backdropSaturate: ['hover', 'focus'],
      }
    }
  }

Disabling

如果您不打算在您的项目中使用 backdrop saturate 功能,您可以通过在配置文件的 corePlugins 部分将 backdropSaturate 属性设置为 false 来完全禁用它们:

  // tailwind.config.js
  module.exports = {
    corePlugins: {
      // ...
+     backdropSaturate: false,
    }
  }
